Investigation on the Utilization Ration of H_2O_2 in the Treatment of Organic Wastewater by Fenton Process

The factors which influence the utilization ratio of H2O2 in treating organic wastewater such as DISTILLED YELLOW WATER,paper making wastewater by Fenton reagent were preliminarily investigated.Experimental results show that the operating conditions such as the dosage of H2O2,the concentration of Fe2+,pH,reaction time are major affecting factors,and that the preferable conditions are as following: initial pH value of 3～4,stirring for 90 min,the addition amount of H2O2 of 4 ml·L-1,the dosage of FeSO4·7H2O of 0.2g·L-1.
